Article
This research paper have evaluated the performance of durability of fibre-reinforced concrete through various test methods exposed to pH 4.5 solutions for 27 months with uncracked and precracked beams. The structural fibres used in this study were hooked end steel, polypropylene (PP) and polyvinyl alcohol (PVA) fibres and the strong acid solutions...
Article
This article compares the test results of the conventional beam approach to those of the Brazilian test related to the durability of fibre-reinforced concrete. The flexural test was found to have some limitations for durability evaluation. On the other hand, the Brazilian test was found to have unique advantages for ingress of saltwater solutions i...
Article
The continuously increasing amount of crushed stone powder normally coming from the production of crushed aggregates or sawing stone has led to an increase in the waste disposal costs or instances of improper disposal. In this study, the effective methodology to increase the utilization of crushed stone powder was studied by considering CaO/SiO2 mo...

Watershed-scale modeling can be a valuable tool to aid in quantification of water quality and yield; however, several challenges remain. In many watersheds, it is difficult to adequately quantify hydrologic partitioning. Data scarcity is prevalent, accuracy of spatially distributed meteorology is difficult to quantify, forest encroachment and land...

Land use and climate change have long been implicated in modifying ecosystem services, such as water quality and water yield, biodiversity, and agricultural production. To account for future effects on ecosystem services, the integration of physical, biological, economic, and social data over several scales must be implemented to assess the effects...
Poster
The provision of water from the Soyang Reservoir is a highly valued ecosystem service by a significant percentage of the South Korean population. In order to maintain the benefits obtained from this service, sufficient levels of water quality and water yield must be sustained. Nutrient elements have a strong influence on the Reservoir water quality...
Article
A conventional flexural beam test subjected to environmental conditioning, especially cyclic wetting and drying, results in a non-uniformly damaged specimen at the cross section as well as non-uniform stress distributions. Some limitations for durability evaluation can cause an erroneous behavior of fiber pull-out. To obtain a uniform stress distri...

Sustainability challenges are transforming science and its role in society. Achieving sustainable use of resources that best supports human well-being requires wise planning of land use and management practices at landscape to regional scales. At regional scale, supportive services from natural resource use are of two types: locally derived via eco...
Article
Polypropylene (PP; 0.5%), polyvinyl alcohol (PVA; 0.75%), and hooked-end steel (1%) fibers were investigated to evaluate the durability performance of fiber-reinforced concrete (FRC) exposed to severe environments. Conventional beam specimens (100 × 100 × 360 mm3) were prepared and exposed to three types of conditioning systems for 27 months, in bo...
Article
This study investigated the transport properties of fiber types in concrete to evaluate their effect on the corrosion of steel reinforcement. The fibers used in this research are polypropylene (PP), polyvinyl alcohol (PVA), and hooked-end steel fiber (Steel). The addition of PVA fibers having relatively good resistance to transport properties indic...
Article
High brightness LEDs (HB-LEDs) carry a high prospect for general lighting applications. Competing with the cost/performance ratio of current light sources demands an increase of the overall efficiency as well as the reduction of the device cost. Since packaging accounts for 30%–50% of the cost of HB LED manufacturing, moving from die- level to wafe...
Conference Paper
The ITRS roadmap for high-density TSV interconnects specifies maximum layer thicknesses of 5-15 µm in 2013 with a sub-micron layer-to-layer alignment accuracy. For 3D chip stacks with multiple layers it is not only necessary to handle and process such thin layers, but later on these thin layers have to be stacked and bonded. When it comes to wafer...
Conference Paper
The advantages as well as the technical feasibility of through silicon vias (TSV) and 3D integration have been widely acknowledged by the industry. Today the major focus is on the manufacturability and on the integration of all the different building blocks for TSVs and 3D Interconnects. In this paper the advances in the field of thin wafer process...
Article
We developed low-temperature, defect-free Cu-Cu direct bonding processes with high interfacial adhesion energies. The quantitative analyses of the interfacial adhesion energies and seam voids of Cu-Cu bonds performed with varying process parameters showed that bonding temperature and post-bond annealing have the most significant influence on bond p...
Article
Cu-Cu direct bonding facilitates fine-pitch interconnection with low electrical resistivity and high electromigration (EM) resistance. However, reliable Cu-Cu bonds result only from high temperature, high pressure and long process time mainly because of its tendency to generate a native oxide that negatively impacts device reliability. Presently, h...
Article
We developed total solutions for the optically aligned Cu-Cu direct bonding process. The quantitative analyses of the interfacial adhesion energy and seam voids of Cu-Cu bonds performed with varying process parameters showed that bonding temperature and post-bond annealing have the most significant influence on bond properties. By optimizing experi...
Conference Paper
The international consortium project TERRECO (Complex Terrain and Ecological Heterogeneity) applies a transdisciplinary modelling approach to examine current and potential future natural resource use within the largest reservoir system of South Korea, Soyang Lake Watershed. Due to intensive fertilization, small catchments within the watershed expor...
Article
Cu and Ti films were deposited by sputtering on thermally oxidized Si wafers and then the deposited films were bonded by direct Cu-Cu thermo-compression bonding for evaluating the effect of the wet pre-treatment on the interfacial adhesion energy. The interfacial adhesion energy was evaluated as 0.29, 1.28, 1.64, 1.17, and 0.42 J/m2 by acetic acid...
